A new meta-analysis combined 35 randomized controlled trials covering 1,211 trained athletes to directly compare creatine, dietary protein, and omega-3 supplementation across strength, endurance, and recovery outcomes. The analysis ranked each supplement by how much additional benefit it produced when added to a baseline training and nutrition routine.
What makes this study notable is that it is one of the few analyses to compare these three supplements head-to-head in athletes who were already eating structured diets. That design changes how the results should be interpreted: the ranking measures marginal benefit on top of an already-adequate foundation, not which supplement is the most fundamental to performance.
Read in that frame, the finding makes sense. Once an athlete is consistently meeting protein needs, adding more protein has progressively less to do. Creatine and omega-3 operate on different pathways than amino acid availability, which is why they continue to produce measurable gains where extra protein no longer does.
